IMPROVEMENT IN TIME-REGISTERING CLOCKS.

Specification forming part of Letters Patent No. 210,788, dated December10, 1878; application liled J une 3, 1878.

To all whom it may concern:

Be it known that we, ZENAS M. LANE, of Rockland, county of Plymouth,State of Massachusetts, and WARREN S. HILL, of Boston, county ofSuffolk, State of Massachusetts, have invented an Improvement inTime-Registe rin g Clocks, of which the following is a specifica tion:

This invention relates to a time-registerin g clock adapted for factory,store, school, or other purposes, to registerfor workmen, clerks, orscholars the time of their arrival or departure, or both.

In this invention certain registering-wheels moving in unison, one withthe hour and the other with the minute hand of a clock, and providedwith embossing figures or characters, are placed in such relation onewith the other, and are so movedto indicate correct time, that a key andpad cooperating therewith, set in motion by a workman, clerk, orscholar, such person being provided with his or her own key, will causea recording-strip, preferably paper, to be pressed in contact with theregisteringwheels, thereby indicating the hour and minute when suchoperation takes place, and with whose key.

1n this way it will be obvious that the arrival and departure of eachworkman may be kept upon the recording-strip, subject to examination, asmay be required, and a person to keep the time of arrival and departureof workmen may be dispensed with, this registering mechanism or clockkeeping the workmens time faithfully.

Figure 1 represents, in front elevation, a time-registering clockcontaining one embodiment of this invention; Fig. 2, a side elevationthereoi', partly in section; Figs. 3 and 4, details of the mechanism foroperating the drum or wheel which acts to feed the recording-strip; Fig.5, a view of the strip-receiving reel or drum; Fig. 6, a sectionaldetail thereof; and Fig. 7, a detail to be hereinafter referred to.

The uprights a Z) or frame are of suitable size and shape to sustain theworking parts. The registerin mechanism herein described is set inmotion by a clock-train shown inclosed between the platescd, supportedby the uprightb. This elocleti-ain, driven by a strong spring in thebarrel 0, or by a weight, is and may be of any usual or suitableconstruction, and need not, therefore, be herein specifically describedfurther than to say that the axle f is that which corresponds with thataxle in a clock which sets in motion the minute-hand, and that the axle9, set in motion at a slower speed by the train of gear 2 3 t 5,corresponds with that axle which sets in rotation the hour-hand of aclock. Upon axle f is attached the minute-register, (shown as a wheel ordisk, 1a,) and upon axle g the hour-register, (also shown as a wheel ordisk, 71

The former-wheel is provided with figures or points to indicate minutes,and the latter with figures or points to indicate hours, (see Fig. 1,)and the peripheries of the two wheels or disks are so moved withrelation to each other by the clock-train that the hour and minutefigures will come opposite each other, and always indicate, on a certainlinein this instance, a vertical linethe hour and minute as accuratelyas would a clock.

To render these registers available for recording time of arrival and,if desired, departure of workmen, &c., a recording-strip, 2 of paper orother suitable material, mounted on a reel, j, and passed betweendirectingrollers k and feed-rollers Z n, and thence to a receiving-reel,0, is placed in front of the registers,

and a pad, 1), and key q are made at the time of arrival or departure ofthe workman or oth er person to force the recording-strip against theregisterwheels, and record for that person designated by the letter,figure, or character upon the end of the key his or her arrival ordeparturc.

The pad 1), preferably of leather or other soft or yielding material, isshown as attached at the end of a plunger, 1', in a sleeve, 5.

The key g has at its inner end a head, 8, the face of which has upon ita raised letter or other character proper to designate one workman, (abook of reference being kept to indicate to which person each keybelongs,) and along the body of the key is a I111, 10, to enter a slotin the plunger, (see Fig. 2,) to main tain the key in upright position.This tin is notched, as at 11, as is also the shank of the plunger 9',to permit the cam t or an arm or too on the shaft a, when turned by theworle record of hours and minutes there also appears a letter,character, or number to designate a person, and subsequent inspection ofthe strip will show the arrival or departure of each person owning andoperating a key.

The key, when the cam t is elevated into normal position by the spring00, connected with the clock-ease 3 or other bearing, and with the hubof arm a, may be easily and freely inserted and withdrawn from theplunger.

The screw 1) in sleeve 8 (see Fig. 1) enters a groove in the plunger andinsures the movement of the latter in a right line, and the spring 0retains or moves the plunger backward from the strip when the handle '11is released, a portion of the plunger also acting upon a portion of thefin 10 of the key to simultaneously carry it backward from the strip.

The peripheries of the directing-rollers k and feed-rollers are soplaced that the strip is retained from contact with the face of theregisters h m, except when moved positively by the pad.

An apparatus or clock of this kind kept in a certain place and operatedby a watchman, so as to move forward only the pad, would indicate thetime of such visit.

In Fig. 2, 01 represents the front portion of a case to inclose themechanism so far described, and the dial 6 is like that of an ordinaryelock, hour and minute hands h m traveling over such dial, all as usual.In this instance of this invention it is provided that the apparatusalso indicates visibly t0 the workman or other person looking at it theactual time. Said minute-hand derives its motion from a beve1-pinion,fon axle f, it engaging a bevel-pinion, g, on shaft t, connected bybevel-gears (see Fig. 2) with a shaft, f, the latter held in a longbearing, 70, at the top of pieces a I).

The hour-hand derives its motion from shaft f, through the train of gear12, 13, 14, 15.

It will be obvious that the shafts f f which operate the register m, andalso the minutehand, move in unison and at the same speed; so theapparatus will operate as a clock only, or as a register, or for bothpurposes. I

The arm a on the shaft u, at each forward movement of the pad andplunger, through the link I, lifts an arm, n, provided with a pawl, 0,so that it is made to travel over and engage a different tooth of aratchet, p, on

the shaft of the feed-wheel n, and as the arm descends after theoperation of the plunger the feed-wheel is rotated far enough to carrythe portion of the strip just embossed or printed beyond the action ofthe plunger at its next forward movement. This feed-wheel n is one of apair, Z n, geared together by toothed wheels so as to rotate in unison,their peripheries engaging the strip at both sides.

The toothed gear on feed-wheel n meshes with an intermediate pinion, 0",which engages a pinion, 8, connected with a hub, t, provided with afriction device, it, and mounted upon a stud or pin, w, the frictiondevice engaging one head of the receiving-reel 0 also on said stud, androtating said reel to wind up the strip 2'. This reel may be removed byturning down the holder m so that it falls in line with stud w.

Shaft '11 is supported by a bracket, a, and the end of axle f takes abearing against a spring, b

The reel 0 has at its barrel a strip-holding spring, 0 by which toattach the end of the strip to the reel.

If hours only are to be recorded the minuteregister may be omitted.

Instead of the disks h m'the figures might be arranged on cylinders orother shaped registers suitably moved progressively past the presser.

If desired the hour and minute registers and pad may be duplicated andplaced side by side, so that several workmen may register their timesimultaneously.

We do not claim a type in connection with one of two time-wheels toindicate the i111- pression of one wheel fromthat of the other.

We claim 1. In a time-recording apparatus, registers for hours andminutes, and a reciprocating pad and key, arranged in a carrier orplunger common to both, to record the time and impress upon a strip acharacter or letter to indicate a person, substantially as described.

2. In a time-recording apparatus, registers for hours and minutes, apad, a key, a carrier or plunger common to both, and mechanism toreciprocate the pad and key, to emboss or impress upon a strip the timeand acharacter or letter to indicate the person, substantially asdescribed.

3. The plunger 7' and pad 1), and registers h m, and the key 9, providedwith a notch, 11,

combined with a bed, w, interposed between the registers, substantiallyas described.

4. The sleeve s and notched plunger and key, combined with the cam t andshaft 10, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
